PLUMBING-FIXTURE.

Application filed January 9, 1913.

' tures, of which the following is a specification.

i The invention relates to plumbing fixtures employing bowls andflushing-means such as water closets, clinic slop sinks, urinals,

and the like, the drawings illustrating the application to a clinic slopsink. The invention has for its primary objects; the provision of anapparatus of the character specified in which the jet means is arrangedin a new and advantageous manner for securing accessibility andefficient action; the provision of a flushing means having its outletportion removable andv adjustable to provide for varying water pressureconditions and at the same time acting as a drainage fixture; theprovision of means whereby the flow of water to the flushing rim may begoverned to suit conditions; and the provision of a jet' plug so'locatedthat it can be used asa drain fixture. Certain embodiments of theinvention are illustrated in the accompanying drawings, wherein Figure 1is a plan view of a clinic slop sink of the wall type, with myimprovement applied thereto; Figs. 2 and 3 are vertical sections throughthe sink, on the lines IIII and IIIIII respectively of Fig. 1; Fig. atis a vertical section through a modified form of sink of'the floor type;Figs. 5, 6, 7, and

8 are enlarged jdetail views of the jet plug employed in theconstruction of Figs. 1, 2, and 3; Figs. 9, 10, 11,12, and 13 are detailviews of modified types of jet. outlet constructions, and Figs. 14, 15,and 16 are enlarged detailviews of the means employed for regulating theflow of water to the flush ing rim of the bowl in the construction ofFigs. 1, 2, 3, and 4.;

Referring to the construction. shown in Figs. 1, 2, and 3; 1 is thebowl, preferably of vitreous material, provided with an upwardlydirected outlet passage 2 leading from the lower end of the bowl cavity,and

with a rim passage 3 opening downward to provide the usual rim flushingmeans.

Flushing water is supplied to. the apparatus at the inlet connection 4,which inlet connection leads to the passage 5 (Figs. 1 and 2). Asindicated in Fig. 2, the forward end of Specification of Letters Patent.

PatentedMar. 2 3, 1915. Serial No. 741,003.

the passage 5 is turned upward'to supply a flushing jet through the plug6 for the passage 2. The front end of the passage 5 is continuedlaterally past the plug 6 as indicated in Fig. 1, and merges into thepassage 7 (see Fig. This passage 7 extends laterally and upwardly andsupplies 7 the rim cavity 3.

The provision of the removable flus ing plug 6 constitutes one of thefeatures of my invention, such plug being shown in detail in Figs. 5, 6,7, and 8. As indicated in Fig. 6, the plug 6 is threaded into a socket 8which in turn is threaded into a collar 9, the parts 6,8, and 9 beingpreferably of some non corrodible metal. The threads on the collar -9are preferably left hand, while the threads on the sockets 8 are righthand, so'tha't in unscrewing the socket 8 thereis no tendency to unscrewthe collar 9. The stem 12 of the plug 6 is preferably of spider form topermit of the ready flow of the water beneath the head 13 of the plug,and the head 13 has its periphery spaced away fromthe surrounding wallof the bowl so as to providethe annular jet opening 14. The center ofthe plug is also provided with a jet pasv sage 15, so that a solid jetof water is directed through the outlet passage 2 (Fig. 2), and anannular jet passing close to the walls of the outlet passage 2 is alsodirected through such passage. The peripheral annular jet in the passage2 serves to eliminate the'friction between the body of water in thepassage and the walls of the passage,

so that a much lower pressure through the opening 15in the plug 6 isrequired than if no annular jet were employed. Tho action of the deviceis also rendered more effective by causing the walls of the passage 2 todiverge gradually from the lower end of such passage to the upper endthereof as indicated in Fig. 2.

The removable jet plug construction as above. described is advantageousfol-several reasons. I In the first place a drainage passage is providedby this arrangement, the plug being at substantially the lowest point ofthe bowl cavity and its removal giving ready access to the passage 2, sothat such passage may be readily cleaned out if it belot ,7 material ofthe bowl 1 second place the construction permits of ,an adjustment ofthe supply passages through" and around the plug to suit varyingconditions of Water pressure. The plug 6 may readily be removed andanother plug of such dimentsions' as to give a different flow readilysubstituted, or the passages through and around the plug may be readilyvaried by means of a file or other tool. It will also be seen that anyforeign article tending to clog the opening through theplug'itself maybe easily removed when the plug is taken from its position in the wallof the bowl. g

'In order to regulate the flow of water through the passage 7 to the rim3 the regulating device 16, shown in position in Fig. 3 and in enlargeddetail in Figs. 14:, 15, and

"16, is employed. This device 16 is provided at its upper end with aplate-like member 17, and at its lower end with a threaded stem 18, thelatter engaging a socket 20 screwthreaded into the collar 21. The socket20 and col lar 21 are provided respectively with right and left handedthreads as in the socket 8 and collar. 9 heretofore described,and'themember 16 is held locked in any position of rotary adjustment, bymeans of the locknut 22. ltwill. be seen that the plate 17 servesto'obstruct the flow of water through the passage 7 more orlessdepending upon its rotary position of adjustment. Tf turned edgewisewith respect to the water flowing through the passage very. littleresistance is offered, while if turned flatwise with respect to thefiow'of water, such flow is very materially cut down. By thisarrangement the supply of Water to the rim can be easily regulated tosuit allconditions of pressure and'proportiomthe flow of water to therim to that of the jet means for the outlet passage 2. This not onlyavoids a Waste of water in many cases, but renders the operation of theentire flushing system morev positive and efficient, as too much or toolittle water to the rim interferes with the proper operation of theflushing means for the outlet passage. The socket 20 may also be used asa drain plug for the bowl.

Fig. 9 illustrates a modified form of jet device wherein the removableplug of the structure heretofore described is done away with and the jetmeans is integral with the As in the other form of construction, a plate13 is provided with an opening 15' in the center, the plate 13 at itsperiphery being spaced away from the inclosing wall of the bowl toprovide an annular flushing space 14'.

Fig. 10 illustrates another modification of the jet means .in which theplate13 is carried by the bowl 1 and arranged so as to providetheannular flushing space 14?, there being in thisv construction,however, no central flushing orifice.

The flushing construction shown in Fig.

1'1"difiers only slightly from that shown in stem 12 integral with thewall of the bowl 1 The annular flushing space 14 is provided as in theother types of construction.

In the construction of Fig. 12 the plate 13 is supported from its edgesby means of the solid portion 23 instead of by means of a stem extendingrearwardly from the plate as in the construction of Figs. 9, 10,- and11. The annular space 14 is thus an interrupted one. The plate 13* isprovided at its center with a flushing orifice 15 In the. constructionFig. 13 the-platele is supported as in the construction of Figi 12, thusproviding an interrupted annular space 14 but in this construction-nocentral discharge orifice is provided.

Fig. 4 illustrates a clinic slop sink of a type somewhat different fromthe structure of Figs. 1, 2 and 3, the primary difler'ence residing inthe'fact that the sink is supported from the floor upon a base 25,instead of being supported from the wallas in the other type ofconstruction. In this structure 1 is the bowl, 2" is the upwardlyextending discharge passage which turns at its upper end and dischargesthrough the passage 26, 3 is the flushing passage in the rim, a is thewater inlet connection. and 5 is the passage leading to the jet plugb.

The rim cavity 3 is supplied with water .through the passage 7 6 1nwhich is located an obstructing plate 17. 27 is the usual bidet washoutmeans employed in all-clinic sinks. The plug 6 and plate 17, and theparts carrying these parts are precisely the same as in the. type ofconstruction shown inFigs. 1, 2, and 3, so that n'ofurther descriptionthereof is necessary. As in the type of apparatus shown in Figs. 1, 2,and

' 3 the outletpassage 2 gradually increases in diameter from its lowerto its 'upper end, thus reducing the friction and lessening theliability of stoppage.

I The volume of water in the passage 7 is much less in the apparatus ofFig. 4: than that of the apparatus of Figs. 1, 2, and 3 which factrenders the apparatus of Fig. 4 less advantageous, as there is a smallervolume of water to flow into thebowl after the supply of water to theapparatus under pressure is cut off. In the apparatus of Figs. 1', 2,and 3 the combined volumes of water in the rim cavity 3 and passage 7 issolarge that no provision need be made for supplying the bowl after theflushing operation. Y I
